To all whom it may condom.)

Be it known that I, EDWARD C. WOOD, of

' Somerville, in the county of Middlesex and ordinary way is constantlychanging by reason of the waves, the tide, or current, some difficultyhas been experienced in maintaining a durable electrical connectionbetween it and the source of electricity because the cable carrying theconductor, however thoroughly it is protected, sooner or later is chafedas the buoy changes its position, either against one of the chains whichmoors the buoy. or against the bottom of the ocean or the river in whichthe buoy is moored so that the line is short circuited. This chafing isalso liable to occur where the signaling apparatus is mounted in theordinary manner on a tripod which stands on the bottom although in thiscase the liability is much less, but ,the mounting of the signalingapparatus on a tripod is not satisfactory owin to the irregularities ofthe bottom on whic the tripod is to stand and its liability to beoverthrown under certain circumstances.

My invention therefore comprises a buoy for supporting an electricallyoperating apparatus whic buoy is moored by a plurality of cables eachattached at one end to a suitable anchorage, one of these-cables carryintheincoming and return conductors Whic form part of it and beingprotected and strengthened bysuitable armor. In this casethe conductor.cable is kept taut by the bug and has suitable means connecting it to .te buoy, the anchorage, and the feeding conductor so that when set thecable while taut will adjust itself to the conditions of its use. So faras I know an electric cable has never formed one of themoorings of abuoy, and the elements which enterinto ts use under these circumstancesare all new;

. My invention will be understood by refer-b Specification of Letters.Patent.

ence to the drawings in which one embodinent thereof is shown,

Flgure 1 is a side elevation of a sub-.Q

merged buoy moored in the manner above f '60 referred to. Fig. 2 is atop view of the junctlon box .by which the conductor is connected to thefeeding conductor. Fig: 3 is a similar view partly in horizontal sectionand partlydn plan. Fig. 4 is a side elevation, and F1 5 .is a. ertl alsection of he. same box. ig. 6 shows in vertical section the preferredform of anchorage, together with the connection of the junction boxthere- -With, Fig. 7 being a plan of the apparatus shown in Fig, 6. Fig.8 is a detail of the joint as will be explained below,

Fig. 9

shows a means for attaching the cable to the 1 buoy. Fig. 10 is a detailshowing the construction of the preferred form of cable,- and Fig. 11shows a modification of the anchorage.

My invention in these drawings is shown applied to a submarine signalingbell which is operated by electricity. Such bells are well known in theart and their construction need not be specifically described. They aresu ported some distance below the surface 0 the water in order that thetone may have proper carrying ossibilities.

1 In the present case. A is a buoy of ordinary construction from whichis suspended the'casi'ng B containing the electric mecha nism for ringinthe bell, and below that the bell itself The buoy is provided with astem A extending through its top and prov ded with'hooks A by whi h itmaybe grappled and hoisted should occasion arise and also with an eye Aby which it may be lowered when being set. 'The buoy is'rnoored at somedistance below the surface of the water by a chain cable C attached atits lower end to a suitable anchorage c in any usual way and also by thecable D which is of special, construction containing within it the wires(Z which form the conductors connecting the electrical mechanism withinthe casing B with the shore station (not shown) from which electricityis supplied to ring the bell. Each conductor is insulated and theconductors together are also surrounded with insulating material (1 ofsuificient thickness and of such character as not to be acted upon anddisintegrated by water and around this in sulating coating I prefer to.vwind two layers,

. comprises a bottom plate f having an openeach comprising a number ofwires d'-,-one layer being given a right-hand wind and the other aleft-hand, these layers forming an armor to protect the insulation andthe conductor generally and add to the strength of the cable. Suchanarmored conductor is not in itself new.

The anchorage in its preferred form (see Figs. 6 and 7) comprises ablock E of stone or the like of sufiicient weight for the purpose and toit is bolted by the bolt 6 an anchor frame F. This frame as'shown ismade of a single casting of cast iron and for the part connected to eachring. The

ring G at one end of the anchor frame carries by means of its'trunnionsg a clamp box H and the ring G at the other end of g the junction box J.

the anchor frame carries by its trunnions The clamp box H comprises twoplates k, h, and a cylindrical casing b the whole being bolted togetherby bolts k From the plate 11. projects two arms 72., the further 1 endsof which are perforated to receive the trunnions g of the ring G. Thusthis clamp box'has a movement in a vertical plane because it is carriedby the trunnions g and it has a movement in a horizontal plane becausethe ring G is supported by the trunnions g'. The cable is attached tothe clamp box H in the following manner: The plate 71. has an'openingthrough it 'to receive the cable D and it is also provided with a throatextending inwardly having an enlarged portion h at its inner extremityaround which the armor'portion of the cable is bent, the

. armorportion of the cable being cut and its end rolled back around theenlargement k and hammered into place against the smaller portion ofthe-throat and secured withwire at its ends. The casing 72. is thenforced over it, the plate h adj'usted and-the whole clamped together bythe bolts h The upper end of the cable D is attached to the buoy A in asimilar manner (see Fig. 9), the clamp box H being identical in gen--eral character with thatshown in Figs. 7

and 8, and being similarly connected to a ring Gr like the ring G bytrunnions g A is a yoke piece bolted to the buoy. Thearms of this yokepiece are perforated to receive the trunnions g of the ring G Thus thesetwo clamp boxes H, H are connected, the

one to the buoy and the other to the anchorage .by a double or universaljoint; The yoke piece A has a passage a through it for the cable whichis attached'to the clamp box H in the same way as it is attached to theclamp box H and stripped of its armor is led to the casing B containingthe electrical mechanism. Its armor being removed it. is renderedflexible for making the necessa ly connection.

s stated above, the anchor frame shown in Figs. 7 and 8 is perforated atits farther end. to receive the trunnions 'g of the ring G and to thetrunnions g of the ring G is attached by arms J the junction box J. Thejunction box (see Figs. 2 to 5) has a cover J which is bolted to it, agasket being used to make a tight joint. The cable D from.'which thearmor has been stripped is; led intoit and spliced as at d in anysuitable way. The box is thereafter filled with some insulating materialsuch as ozite as indicated at y, the'gasket and cover are then appliedand sea-led by a coating of ozite as shown at j, thus making the wholewatertight. Thus it serves to protect the splice and with the anchorframe to guide and protect the cable between the clamp boxes. At eachend ,of the junction box is provided a stuffing box j 3' through whichthe cable enters or leaves the junction box as the case may be, and atits outer end the F box is provided with a threaded opening j The arms Jabove referred to form a yoke spreading from a plug 7' which is threadedand screws into the opening 3' The plug 7' is recessed and the closedend of the recess is perforated as at y" to allow the passage of theunarmored cable through it. Within the recess and arouhd the wires isplaced a perforated compressible washer j and a perforated followerv jhaving ears 9" with holes to'receivescrews i which screw into holes inthe plug y' When these screws are screwed up as far as possible thewasher 7' will be compressed by the follower'and leakage at that end ofthe junction box will be prevented. At the other end of the junction boxthere is a recess 7' provided, which is perforated at its closed end forthe outgoing conductors. A perforated compressible washer j is alsoprovided as before and. a perforated follower j forming part of theplate It sets into the recesses and is clamped against the washer j bymeans of screws j which pass through the plates of the clamp frame H andinto bosses j on from this description that the main strain on the cableD is taken up by the armor d by means of which the cable. is connectedby the two clamplboxes, at one end. of the buoy at the other end to theanchorage, and

that the armor being. removed between. the clamp box H and clamp box Hthe cable is rendered flexible for passage through the anchor. frame tothe junction box and, for

splicingwith the feed cable D The-cable v is thus held so securely andis. so protected that. there is no danger of chafing of the insulatingmaterial on the conductor at the only position where it isunprotected.By removing the-armor. from so much of the cable as passesthrough theanchor frame it is rendered flexible-sothat it may adjust itself asoccasion requires, the anchor frame a section of pipe 70 which serves toprotect the conductor as it passes from the clamp frame to the anchor:frame. The clamp box in this case lettered H? is similar to the clampboxH. The ring Gr in this case is connected by its ,trunnions. g to thearms H of the clamp box H and by its trunnions g to a yoke piece havingarms H and a socket H into which screws the outer end of the pipe k aThe above are given. as convenient em- I bodiments of my invention,simple to construct and effective in operation. For ordi nary uses Iprefer the form shown in Fig. 1, but the anchorage shown in Fig. 11allows a slight play of the cable, the pipe holding it off bottom.

universal joint though technicall For convenience of expression thejoint provided by the ring G may be termed a it is not such, and it isevident that this orm of joint is but one of anumber of well knownjoints which may be used for the purpose.
